It’s the end of our Spring term, and yes occasionally somebody can’t sign on to their Oracle instance because their event log is full. They get the following message on Winodws:
C:\>sqlplus / AS sysdba SQL*Plus: Release 220.127.116.11.0 - Production ON Wed Jul 15 10:19:37 2009 Copyright (c) 1982, 2008, Oracle. ALL rights reserved. Enter password: ERROR: ORA-28056: Writing audit records TO Windows Event Log failed
The fix is simple, just delete your items from your Windows’ event log.
